To all whom it may concern: 4

Be it known that I, PEMBROKE D.HARTON, v a citizen of the United States, residing in Fhilaclelphia, Pennsylvania, have invented certain Improvements in Cake-Coating Machines, of which the following is a specification.

My invention relates to cake coating machines; and the ohjectof my invention is to provide a machine for @iepositing soft dough,

macaroon, melte fondant, chocolate, marshmallow paste, or other material of a similar or like nature, upon the surface of halted cakes which are feel by suitable means to a common depositing point.

My invention is fully shown in the accompanying drawings, in which:

Figure 1, is a side elevation of the complete machine forming the subject of my invention; Fig. 2, is a plan View oi" the same;

Fig. 3, is a sectional elevation looking in the direction of the arrow :0, anti taken on the line a-a, Fig. 2; Fig. 4, is an enlarges. sectional view of a part the structure, showing the application of the coating material to the cakes, antl Fig. 5, taken on the line b o, l.

tiy present machine embodies certain improvements in the structure of my prior Fatent No. Sal 03, April J 3388, includes certain details of my several gentling applications relating to coat of cakes. i-

nrovi es a common point we ciepositec h 2 of a suction or vacuum; over which a. belt is a sectional'view,

; while the other member a hopper, into which coating material is placed, which hopper is divided by a movable partition plate 2 which plate may extend into the discharge passage for the material vwhereby I may provide means for effecting the deposit of two kinds of material upon the cakes. The hopper iscarried by a suitable supportin arm 3 extending from a bracket 4, which arm is longitudinally aperturecl at 5 for the passage of a feeding structure which is combined with the partition plate. ihis feeding structure comprises feeding passages 6 on the opposite side of said partition plate for two kinds of material. The lower end of this feeding strncturehas its outer walls grooved at 7, and disposecl in registry therewith is a memher'S forming part ()1 u e material cle iivery spout. This member is secureti to the feecling structure by means of plates 9 secured by screws 10.

The coil spout proper comprises a portion 11 arranged telescope the portion 8, and springs 12 are provided to return it to the lowered position aiter it engaged the cake. in the present instance this structure comgirises angle pieces 13 14-, one of which carries a member 15 which "forms the side wall. and 01 one side of the (lelivery spout, anti the other carries a memher 16 which "forms he wall of the other spout. The first with a series of holes from each of which clepemi nozzles 18, a plate 19 se cur-eel thereto with series nozzles 36- surrounding the nozzles 18 whereby the r' i tiiiiering color or he on the he eatruclecl nozzles til clir 26 to the open position, and under the suction created therein such cakes will be held in place. The nozzles for delivering the material to be deposited are then lowered into contact with the cakes, and compression of such material within the feeding structure due to the telescoping of one part with respect to the other as described, will cause such material to flow onto said cakes, and during such action the feeding means are replenished with such material to be deposited. This is accomplished in the following manner: The hopper for the coating material has its bottom openingnormally closed by plates or ribs 30 disposed on both sides of the central partition plate 2 and lying at a point just below the bottom wall 31 of said hopper. Arranged tomove opposite the feeding device in the wall of the same, are'pistons 32 connected -at' 3 3 to links 34:, which links are in turn connected to bell-crank-levers 35 pivoted at 36 and operated by means of rods 37 from cams 38 driven by the main driving shaft of the ma chine. .Upon lowering the feeding device, the central partition plate carries the material down, and the ribs 30 of the same.

close off the connection of the material in the upper part of the structure with that in the feeding channel.

Mounted at the sides of the bed late are projections 39, and when the te escopin portion of the feeding structurestrikes said projections, the delivery spout is caused to telescope and eject the coating material accumulated within nozzles.

When the central partition-plate is in the fully lowered position, the pistons are moved out and draw into the spaces 40 a supply of coating material, which supply is just suflicient in amount to take the place of that ejected onto the cakes, and when said partition plate is raised, the pistons travel in and force the coating material into that portion of the feeding channel below the ribs 30. p The lowering of the hopper is timed to occur when cakes are in place over the suction box, and suitable mechanism is employed to efi'ect this action. I

. If desired, 1 may omit one nozzle and feed the material from the other from one side only of thehopper. terial of the same character may be cakes from both nozzles, or sue off we kinds or two c orthe plate 26 forming a valve,

the same from the several tion plate deposited upon boards in the same manneras in the structure referred to in my prior patents.

I claim:

1. 'In a cake coating machine, the combination of means for feeding cakes to a common point, means for maintaining said cakes in such position, a hopper'having compartments for coating material, a vertically movable structure forming .a bottom for said hopper and having a plurality of chambers communicating with said compartments, outlet nozzles communicating with said chambers for the simultaneous deposition upon each cake of coating material from each chamber, horizontally disposed pistons for moving said coating material to the chambers of the bottom structure, and means for moving said bottom independently of the hopper to bring said nozzles into proximity with the cakes.

In a cakecoating machine, the combination of means for feeding cakes, an icing hopper, delivery spouts communicating with said hopper, a partition plate for said hopper whereby the latter may contain material of different kinds for trically arranged delivery spouts, said partition plate carrying the bottom of the hop per which is normally closed, and means for moving said plate whereby the bottom may be opened for the delivery of the material.

3. In a cake coating machine, the combination of a hopper for coating material, a movable partition plate in said hopper, ribs carried by said plate and forming a movable bottom for the hopper, lateral passages arranged below said hopper, feed passages disposed below said lateral passages, said lateral passages being in communication with the hopper when the partition plate is in one position and in communication with the feed passages when the partition plate s in another position, and means for causmg a flow of material into said lateral passages, the ribs of said partition plate form mg a valve and holding the coating ma terial against upward movement when extruded from the nozzles.

4. In a cake coating machine, the combination of a hopper for coating material, a movable partition-plate in said hopper, ribs carried by said plate and forming a movable bottom for the hopper, lateral passages arranged below said hopper, feed passages disposed below said lateral passages, said lateral passages being in communication with the hopper when the partition plate is inthe lowered position and in communication with the feed passages whenlthe partiin the upper position, pistons a flow of material into said latfor causing delivery to .conceneral passages, a delivery nozzle in commu- In testimony whereof, I have signed my nication with said hopper, and means for name to this specification, in the presence of telescoping said nozzle to deliver the coattwosubscribing witnesses.
